For those looking for a source, I looked into it and yes the source is the CCPs claims. We all know how trustworthy CCP statistics are.

According to the Chinese NFI, national forest coverage has increased by 2.15% in the 7th NFI and by 3.41% in the 8th NFI

By contrast, the GFC dataset, which is considered to be more accurate than previous remote sensing datasets due to its unprecedented global high spatial resolution, showed that the change in forest area of China between 2000 and 2012 was a net loss of 38,743 km2, equivalent to a decline of 0.40% in national forest coverage

Basically, satellite imagery seems to "strangely" conflict with CCP figures.

That GFC study contradicts the many studies using both older datasets and newer datasets:

In science, we call this "cherrypicking data." Colloquially, we understand this to be because someone fucked their experimental validation. In the real world, we call this "disseminating misinformation."

global-scale data cannot reasonably represent changes in the regional land cover. Moreover, different studies may have different accuracies within the same region and even may reach opposite conclusions
